3 Description

The BQ51013C-Q1 device is a single-chip, advanced,

flexible, secondary-side device for wireless power

transfer in portable applications capable of providing

up to 5W. The BQ51013C-Q1 devices provide

the receiver (RX) AC-to-DC power conversion and

regulation while integrating the digital control required

to comply with the Wireless Power Consortium

(WPC) Qi v2.0 communication protocol. Together with

the BQ500212A primary-side controller (or other Qi

transmitter), the BQ51013C-Q1 enables a complete

contactless power transfer system for a wireless

power supply solution. Global feedback is established

from the secondary to the primary to control the power

transfer process using the Qi v2.0 protocol.

The BQ51013C-Q1 integrates a low-resistance

synchronous rectifier, low-dropout regulator (LDO),

digital control, and accurate voltage and current loops

to ensure high efficiency and low power dissipation.
